What happen when Projectile launched at an angle

When a projectile is launched at an angle, it follows a parabolic path due to the influence of gravity. This type of motion is known as **projectile motion**. Here’s a breakdown of what happens during this motion:

### 1. Initial Velocity
The projectile is launched with an initial velocity (\(v_0\)) at an angle (\(\theta\)) relative to the horizontal. This initial velocity can be broken down into two components:
- **Horizontal component** (\(v_{0x}\)): \(v_{0x} = v_0 \cdot \cos(\theta)\)
- **Vertical component** (\(v_{0y}\)): \(v_{0y} = v_0 \cdot \sin(\theta)\)

### 2. Horizontal Motion
- The horizontal component of the velocity (\(v_{0x}\)) remains constant throughout the flight since there is no acceleration in the horizontal direction (assuming air resistance is negligible).
- The horizontal distance (\(x\)) traveled by the projectile at any time \(t\) can be calculated using: \(x = v_{0x} \cdot t\)

### 3. Vertical Motion
- The vertical component of the velocity (\(v_{0y}\)) is affected by gravity. The acceleration due to gravity (\(g\)) acts downward, changing the vertical velocity over time.
- The vertical position (\(y\)) of the projectile at any time \(t\) can be calculated using: \(y = v_{0y} \cdot t - \frac{1}{2}gt^2\)
- The vertical velocity at any time \(t\) is given by: \(v_y = v_{0y} - gt\)

### 4. Maximum Height
- The projectile reaches its maximum height when the vertical component of its velocity becomes zero (\(v_y = 0\)). This happens at time \(t = \frac{v_{0y}}{g}\).
- The maximum height (\(H\)) can be calculated using: \(H = \frac{{v_{0y}}^2}{2g}\)

### 5. Range
- The range (\(R\)) of the projectile is the horizontal distance it travels before hitting the ground.
- The time of flight (\(T\)) is the total time the projectile is in the air. It can be calculated by finding the time when \(y = 0\) (i.e., when the projectile returns to its initial vertical position).
- The formula for the range is: \(R = \frac{{v_0}^2 \sin(2\theta)}{g}\), which is derived by multiplying the horizontal component of velocity by the total time of flight.

### 6. Parabolic Path
- The trajectory of the projectile is a parabola. The shape of the parabola is determined by the initial speed and the launch angle.

**Key Factors Affecting Projectile Motion:**
- **Launch Angle (\(\theta\))**: Affects the shape and distance of the trajectory. A launch angle of 45 degrees (without air resistance) maximizes the range.
- **Initial Speed (\(v_0\))**: Higher speeds result in longer ranges and higher maximum heights.
- **Gravity (\(g\))**: Constant acceleration downwards influences the time the projectile spends in the air and the maximum height reached.

This description covers the basics of projectile motion, which is a fundamental concept in physics and is widely used in various applications such as ballistics, sports, and engineering.
